[FFmpeg-user] Capturing raw H264 data. Need to convert to YUV with ffmpeg

[Joseph Rosensweig]

Hi all,

   I've got a program that simply captures h264 data packets, extracts the
payload and appends it to a file.  I've been able to successfully capture
the stream, but it seems like I'm not including some header data that
ffmpeg requires.  Does anybody know where I can find documentation or
information on what FFMPEG looks for in a raw h264 file?  I'm assuming that
I need something to indicate the start and end of frames, maybe the
dimensions, etc.  But not sure where to find info on this...

    Here is my full uncut console output:

$ ffmpeg -r 30 -s 1280x720 -i test.h264 test.yuv
